Process Modeling

Hey Guys, I have a process model where employees can submit a request. The submitted request gets either approved by the manager or employees can cancel the request prior to it being accepted by the manager. For this, I have two user input tasks with the OR gateway where, once the request is submitted it will go on both employees as they can either cancel or not, and to the manager to accept the task. Now, I want to automatically cancel one user input task as another gets executed. Is there any way, it can be configured in the process model. Thank you,

Hey all,  I am trying to have a loop where a counter is increased once per day ( with a timer set to tat interval ). So when the 2nd task is activated, I would be able to subtract that counter from the max of 12 days.  Im quite new in Appian, and I would to know what expression, or how should I configure in order for this to work. 1) created a new variable 2) setup a timer event. Do I need some extra configuration here? 3) on the script task the configuration ( i want to start from 0 days ?) What the best way to configure it ? is it that correct ? Kind Regards,  Victoria

Hi All, I am using add user smart service and when the user is created user should not receive any account creation email  How can we disable 

Hi all I need some help on using the Update Constant Smart Service. The constant in question contains a decimal value intended to be a threshold that a user can change when necessary. I've created a process model with a start node, a user task, the Update Constant smart service and an end node. The process model has a variable of type decimal called threshold. Running the process completes without error, and the changed threshold variable is captured correctly. However when I check the constant, the previous value remains unchanged. The Smart Task is configured with the name of the constant and the threshold process value as inputs. Any advice or examples will be greatly appreciated! Regards Stephen

Hi, I have a process model, like the below attached screen shot. I have taken a "OR" gateway and based on the PV variable value, I need to achieve required activities. Now, the issue which I am facing is, even though I am setting "activity chaining", my process getting stopped at OR node itself. Any idea what to do here.

I have a very simple app so far. There's no database or external process.  Just a few interfaces, with one that shows the content of a folder, given a folder ID.  I added a button to that interface that should send the user to a form where more files can be uploaded to the folder.  I created the below process model, which I'm calling with the below code. When I execute this code, the process stopped at the Document Upload without showing the actual interface.  No errors popped up either.  What am I doing wrong? a!buttonWidget( label: "Add Documents", icon: "plus", saveInto: { folderId: ri!folderId, a!startProcessLink( processModel: cons!DSU_PM_DOCUMENT_UPLOAD, ) }, style: "PRIMARY", )  

So i have one process model that calls around 4 subprocesses . There are two users for whom i am getting the error as mentioned in the Subject. Now there are instances that run successfully and there are like 2-3 instances that fail for not a particular subprocess call. i.e. if one fails in the first subprocess , then second instance fail is on the second subprocess with the same error. yes the user was deactivated before and then added again using SAML. We tried removing the user from the group and re adding the user back. But still the same issue. It isnt a blocker for the user as not all instances are getting this error. But im trying to understand how the system is failing in the middle. Thank you in advance.

Hi readers, I have a process start form where i enter few details(ID, Name, Mail, Comments) and submit the form. the form goes to a admin where he need to approve. There is a approval form, where all the entered details are present and admin can change if any details are need to be changed; for suppose there are some comments mentioned by user, i as a admin need to change the comments and approve. The changed comments and other details entered by user need to be saved in database; that is what not happening; instead original comments mentioned by user are only saving Need to know the reason why this is happening? and what changes need to be done to save the updated/changed comments  

I have a web api that triggers a process model that has more than 50 nodes. Is there a way I can relay an error back as an web api response if there are errors encountered in the process execution. I am aware that I cannot chain the process model as I have exceeded the 50 node limit.

Hello, I need to call a sub-process and assign it to a specific user (I will need the user to be the initiator of the sub-process) BUT I don't want it to be a task as suggest in the "Assignment" tab of a sub-process. Is there another way to pass the user as a parameter without assigning it as a task? Thanks in advance Lionel

Hi, I am using send e-mail smart service to send an email notification which is internally using HTML template. Initially, I have designed a template with few variables using ### and which are working perfect. Later on I have added few more variables, but these variables are getting replaced with values sometime and sometimes those are not loading. I have even tried to click the option "Re-Scan Template" and it worked for some time and again after some time it is not working. Can someone advice on this. Thanks.

Currently have a process that sends an email I want to cc a group and an entered input variable that connects to an email. Is there any way I can send an email to both a group and a process variable? 

Hi, When we have a user input task why do we use start form ? And what is the difference between both of this  What are the use cases of start form and user input form ? Can someone help me please?

I have four sub processes which are going in AND gateway as input but when control comes to And gateway iit s stuck?

I have used query databse service in my process model. Here I wrote this query to update particular fields in database table. I searched on google and i found that active class parameter should be used in query to update database table.  I have made parameter like this and i used these parameters in my above query using ac! . But when i run this model it doesn't move ahead from this stage eventhough there is no error on this stage.  Is my configuration proper?

In my process i have two reasons not to put my start interface in the properties in (process start from): first because i have to check condition before start the interface second because the cycle contains loop and i can't loop to the start node  The Process Model works well in the debugging but it can't be added to site or initiated from Action button

Hi, I am using 'Save draft' functionality on a User task. The user task interface has an editable grid, containing file upload control in each row. The row can be dynamically added or deleted (using the X icon implemented in the top right column - dynamicLink). As explained in https://community.appian.com/support/w/kb/802/kb-1480-unable-to-save-changes-on-a-sail-form-if-an-file-upload-component-is-present-with-uploaded-files 'Save Draft' functionality doesn't work with files temporary uploaded to the form and I have to live without it [emoticon:c4563cd7d5574777a71c318021cbbcc8] However, I have a problem if users uploads a file in a grid row and deletes the row (clearing the grid row item in a grid data source and clearing the save target of the fileupload component contained in the grid row). I am not able to clear the inactive temporary saved file from the memory and Appian keeps preventing the Save draft as the fileupload is still there, although fileu

Hi Team, We have a requirement to get files from external system along with some input parameters to our process model via a web api. The web api which starts a process would upload the file to the target folder and write/update data in respective appian DB tables. How can we achieve this? Request format :  document - type (document/file) id - type int name - type text etc This request can either be in form or json format. Appian version used is 21.1

Hi Team I have a requirement where I need to generate different update query statements for different tables depending on some conditions in a  process model.Do we have any feature to implement this? I do not want to use a XOR gate and create different nodes from XOR condition as the query statements may be huge.Or if we can generate the query statement in a Script Task and directly call the query to update the tables in the process model.We use Appian version 21.1 Thank you!!

i debugged a process but it keep running for infinity and filling the database with the same row

I have a document with 10 pages and I was able to extract pages 1 to 4 using Extract PDF Pages smart service (Start Page = 1 and End Page = 4). The new PDF which got generated has 4 pages. I would like to know whether there is any functionality / service available which would allow me to extract only pages 1 and 4. The new document generated should be having only 2 pages.

I have a requirement where in interface m showing a field in a grid which is not part of CDT . But when I generate document it can only take fields passed in CDT.so I need to pass this extra field as well in excel . Is there any way I can pass the extra field value to the excel

Hello, Any one familiar with this type of error? An error occurred in executing an Activity Class.

Hey Guys, I have a process  model pictured below to reassign tasks. I am using a recipe that I created in a previous app that worked. This process model appears to work flawlessly. The reasignee and task id are updated and stored into their process variables correctly but the task simply isn't reassigned. No errors are thrown and the process model completes without stalling  or failing on the xor gateway or the reassign task node (these are the only two nodes). I have literally nothing to go on since there is no sign of any error. Just that the assignee for the task in the process report simply does not change as it should. 

Hi All, Facing this issue for particular users when using a process model as a link for an Interface card component. The error is . I am using it in a card in the interface Kindly Help. Thanks in advance
